Castlereagh South (District Electoral Area)

Castlereagh South is one of the seven district electoral areas (DEA) in Lisburn and Castlereagh, Northern Ireland. The district elects five members to Lisburn and Castlereagh City Council and contains the wards of Beechill, Cairnshill, Carryduff East, Carryduff West, Galwally, Knockbracken and Newtownbreda. Castlereagh South forms part of the Belfast South constituencies for the Northern Ireland Assembly and UK Parliament.

It was created for the 1985 local elections, replacing Castlereagh Area A which had existed since 1973, and originally contained seven wards (Beechill, Carryduff, Four Winds, Knockbracken, Minnowburn, Moneyreagh and Newtownbreda). For the 1993 local elections, it was reduced to five wards, with Carryduff splitting into East and West and gaining Cairnshill but losing Beechill, Minnowburn and Newtownbreda to the new Castlereagh West DEA. For the 2014 local elections, it was increased to seven wards, regaining the areas which had previously gone to Castlereagh West.
